To provide a planar fluorescent lamp fixture in which light generated from respective plate faces can be used effectively.

This is provided with the planar fluorescent lamp 10 of which the appearance presents a plate-form, and the light is emitted from its both plate faces 11, 12, the planar fluorescent lamp 10 is suspended from a ceiling face for the purpose that its plate faces 11, 12 become approximately horizontal and a reflecting plate 30 to convert the light 42 emitted in the upward direction onto the upper face 11 side of the planar fluorescent lamp 10 into the downward direction is arranged, and the optical characteristics are decided so that a part of the light may be penetrated onto the ceiling face side via the reflecting plate 30.
